Add another layer of soundproofing by eliminating the spaces around the door. Adding weatherstripping around the sides and a door sweep along the bottom will further ensure less sound comes in or goes out of your office.
Seal any holes
Now that your door is sealed, it’s time to close the gaps found around outlets or ducts. Sealing the holes with an all-purpose caulk can reduce how much sound travels from one room to another.
Soften your decor
If you have wood or tile floors, Vila suggests adding a rug or two. Soft fabrics will absorb sound, so consider bringing in an upholstered chair if there’s room, and adding some throw pillows. Another easy fix is hanging blankets or quilts on the walls.
If the blankets or quilts aren’t enough, apply acoustic panels to your walls. These panels range from basic black foam to colors and patterns that can update your room.
If you’re still distracted by outside souinds, a white noise machine might help. By continuously emitting a soothing sound, such as wind or water, the machine can help you block the distractions. A white noise machine can cost anywhere from $20 to $120, depending on the type you buy.
